    1. Hello Giles. A method in Rust is just a function, which also takes a first `self` parameter (similarly to Python). Hence, passing a method is just a matter of using the right types in the function signatures:

      pub struct Greeter {
      greeting: String

      impl Greeter {
      fn greet(&self, name: String) -> String {
      return format!(“{}, {}”, self.greeting, name);

      fn call(name: String, fun: fn(&Greeter, String) -> String) -> String {
      let greeter = Greeter { greeting: “Hello”.to_string() };
      return fun(&greeter, name);

      fn main() {
      println!(“{}”, call(“Giles”.to_string(), Greeter::greet));
